3. The operator places the adjusted aimpoint on the target and pullsthe trigger. Upon firing, the fuze is inductively set in the weaponwhere it will fly along a predictable path and air-burst at the targetarea defeating it and any other targets and/or equipment that maybe in the vicinity of the lethal footprint.
Method of OperationMethod of Operation1. Operator places aimpoint on the target and activates the laser rangefinder.
2. The fire control system computes the distance to burst and provides anadjusted aimpoint based upon target range information, the ballisticcharacteristics of the ammunition and environmentalconditions…transparent to the User.

Force-on-Force TRAC-WSMR Modeling
Blue Company in theOffense
• Force-on-Force• Conducted by TRAC-WSMRusing CASTFOREM
• Initial parametric assessment ofP(I), maximum effective range, and BOIshowed increased effectiveness and asignificant reduction in number of casualties
• OICW AoA conducted by USAIC supportedby TRAC found:
• OICW improves Blue force effectivenessthrough both lethality and survivability
• Extends incapacitation range well beyondlegacy individual combat weapon
• Increases OPTEMPO – virtually eliminating firefightsto destroy a threat even in protected positions
• BOI of 4 per squad performs statistically the same asBOI with more OICWs providing the lethality andsurvivability required to win and fight the next fight

Training Concept Considerations
� Make maximum use of existing ranges� Minimize new special targetry procurement programs� Use simulations to decrease service and training ammunition cost and
allocations� Identify follow-on training device/virtual and live simulation
requirements� Minimize institutional and unit training time without sacrificing
Soldier proficiency

Thermal Imager Demo
� Standing personnel & vehicle target at 500 meters
� MTWS 180 & 60 HFOV
MTWS 180 MTWS 60
A six degree FOV sensor provides high probability of detecting standing personnel sized targets which are barely visible with 18 ° FOV
However other system parameters must be considered e.g. Target Acquisition Time, Superelevation, and System Size and Weight
